Abstract (original English)
In mammals, two types of adipose tissues are present, brown (BAT) and white (WAT). WAT itself can be divided into subcutaneous and internal fat deposits. All these tissues have been shown to present a great tissue plasticity, and recent data emphasized on the multiple differentiation potentials obtained from subcutaneous WAT. However, no study has compared the heterogeneity of stroma-vascular fraction (SVF) cells and their differentiation potentials according to the localization of the fat pad. This study clearly demonstrates that WAT and BAT present different antigenic features and differentiation potentials. WAT by contrast to BAT contains a large population of hematopoietic cells composed essentially of macrophages and hematopoietic progenitor cells. In WAT, the non-hematopoietic population is mainly composed of mesenchymal stem cell (MSC)-like but contains also a significant proportion of immature cells, whereas in BAT, the stromal cells do not present the same phenotype. Internal and subcutaneous WAT present some discrete differences in the phenotype of their cell populations. WAT derived SVF cells give rise to osteoblasts, endothelial cells, adipocytes, hematopoietic cells, and cardiomyoblasts only from inguinal cells. By contrast, BAT derived SVF cells display a reduced plasticity. Adipose tissues thus appear as complex tissues composed of different cell subsets accordin
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
